You’ve seen the commercials where they say “It’s the mirrors.” The marketing oversimplifies things a bit, but the heart of every component using Texas Instruments’ DLP (Digital Light Processing) technology is an optical semiconductor known as a Digital Micromirror Device (DMD). Mounted on hinges, up to two million microscopic mirrors tilt toward (pixel on) or away (pixel off) from the light source in coordination with a high-speed rotating color wheel. DLP technology offers a combination of high resolution and contrast for an extremely bright and detailed image.
Eliminating the conventional cathode-ray tube (CRT) and employing DLP technology has made it possible to shrink the size of rear projectors to less than 20-inches deep with screen sizes 50-inches or more.
DLP technology continues to evolve and in just the last couple of years we have seen incredible performance and price breakthroughs. Here we have listed a number of high-definition DLP products currently available.
We’ve rounded up some of the latest rear-projection and front-projection DLP products:
